What action must you complete before dropping in over any obstructions on swath approach? -
ANS Turnaround
Do not make turns over the following at any time? - ANS Residences, poultry houses,
livestock, and ponds/reservoirs.
Minimum altitude you must maintain during ferrying flights? - ANS 500ft AGL
When ferrying never fly directly over what kind of buildings? - ANS Farm buildings
During ferrying flights it is good practice to do what on each new run? - ANS Deviate course
1/8-1/4 of a miles from your previous course
Aerial application equipment is calibrated according to what metric? - ANS APM or Acres per
minute
DGPS-mediated flow controllers do what? - ANS Adjust flow dependent on aircraft speed
Application height is the distance between what two things? - ANS nozzle tip/spreader exit
, ©THESTAR 2025 ALL RIGHTS RESERVED
plant canopy
Small droplet sprays require what sort of application heights? - ANS Application heights of 8-
10ft above canopy for droplet sizes in the 150-200 micron range
What sort of water could you use for spray pattern testing? - ANS Dyed water
When spray pattern testing with oil based test liquid, what sort of cards should be used? -
ANS Oil sensitive cards
Effective swath is: - ANS The span of the spray pattern that contains enough pesticide to
obtain the desired result/pest control
Overall swath is: - ANS The outermost range that spray droplets within your pattern will
reach but are not enough to result in satisfactory pest control
In what type of outdoor conditions is it best to perform spray pattern testing? - ANS Low
wind conditions generally in the morning, if winds are measurable, fly the aircraft INTO the
wind to conduct spray pattern testing.
What is the first thing you should do prior to conducting a spray operation? - ANS Scout the
target site from the air to identify obstacles, terrain, and field layout
What should you specifically look for when scouting a field aerially prior to an application? -
ANS Breaks in cultivation or plant cover, trees, buildings, telephone poles, guy wires etc.
Guy wires generally pull in which direction in relation to circuitry wire? - ANS The OPPOSITE
side

What must you determine about nearby buildings assumed to have electricity? - ANS The
route by which they get their electricity
If there is an obstruction beside a field, how should it be handled? - ANS Fly close and
parallel to the obstruction
If there is an obstruction at the end of a field, how should it be handled? - ANS One or two
swath widths prior to reaching the obstruction, cut off spray and pull up. After those passes are
complete, fly one or two parallel clean up passes to catch the swaths you cut off early for.
What are the different types of ground crew members? - ANS -On site field crew
-Mix/load crew
-Application equipment servicing crew
What jobs do the On Site Field Crew perform? - ANS -Current weather conditions
-Topographical feature awareness
-Location and dimension of ground based hazards
-Buffer zone delineations
-Other factors affecting the job
The process of "Reregistration" refers to what practice by the EPA? - ANS Reviewing of older
pesticides (those registered before November 1984_ to ensure that they meet current scientific
and regulatory standards.
What process may lead to the changing of pesticide labeling on a product you have been using
for years? - ANS "Reregistration" performed by the EPA
What is the most likely route of pesticide exposure for aerial applicators? - ANS Dermal

Is it true that different handling activities (mixing, loading, applying, cleaning equipment etc)
may require different PPE? - ANS YES, TRUE
The effect of any pesticide depends on which two factors? - ANS -Amount of chemical
absorbed
-Size of the organism receiving the chemical
The measurement of:
-The amount of chemical absorbed
-The size of the organism receiving the chemical
Is referred to as what term? - ANS Dosage
When referring to "dosage" the amount of chemical is measured in what form? -
ANS Milligrams(mg)
When referring to "dosage" the size of the recipient is measured in what form? -
ANS Kilograms(kg)
This example illustrates what key concept?
"a single grain of salt will injure an ant, but not a human" - ANS Dosage
The ability of a chemical substance to cause injury is called? - ANS Toxicity
Dosage is a yardstick that helps classify pesticide toxicity into which three different categories?
- ANS DANGER
WARNING
CAUTION
